Title: Method for confirming transaction information by ic card and its system
Inventor: TANUMA HIROSHI
IPC: G06Q20/00
Filed: 1998-09-21
Abstract: PROBLEM TO BE SOLVED: To improve security in case of losing an IC card, and also protect a non-used sum in case of losing the IC card. SOLUTION: In this method for confirming transaction information, when loading a sum in an IC card, an ID number is assigned to a withdrawn sum from a bank account, and added to a transaction sum paid from the IC card, and in settling the transaction, the validity of the transaction is certified from the ID number. As for electronic money lost with the IC card, the ID number held in the IC card in case of losing the IC card is specified so that only the sum used before the loss processing is withdrawn from the account of the IC card user. Also, the IC card user can set limits (transaction sum, number of times, area, and time zone or the like) to the payment from the IC card in registering the sum in the IC card. Thus, this payment limit items can be checked by a terminal for each commercial transaction.
